Overview

The purpose of this page is to review SPCC refined smoothed analytic segments and compare them to version 1.0. This comparison report is still in development, and further maps and reports will be added as they are developed.

This website compares version 1.3f to version 1.0. Version 1.0 represents the future version of SPCC and provides a baseline for comparison. Version 1.3f includes updated data layers where new data is available in addition to refined measures for evaluating intersection density, building placement, and land use diversity.

1.3f Changes

Version 1.3f uses a new approach to differentiating C-1 and C-2. To quality as C-1, a grid cell must now must have density-diversity-design characteristics below a C-3 AND have some level protection as a park or open space. 1.3f also includes a C-5 overlay that provides an alternative path for C-4 to become C-5 if there is a cluster of civic uses and employment density thresholds are met for C-5.

SPCC 1.0 and SPCC 1.3f Mapping: Refined Smoothed Segments

Note: The Directional Change map only shows changes between detailed analytic classes C1-C6.

Cross tabulation of SPCC 1.0 versus SPCC 1.3f by Linear Feet

The table below provides a tabular comparison of SPCC refined smoothed analytic versions 1.0 to 1.3c. The rows represent linear feet of each classification under SPCC 1.0, and the columns represent liner feet per classification under SPCC 1.3f.
